We are seeing the same "WebGL: context lost" issue on iOS 17 Beta 8 Safari when running our Phaser 3 application using WebGL rendering. The issue occurs while loading the page and locking the device and then unlocking again. Any subsequent reload of the page then causes the same "WebGL: context lost" error. The browser cache needs to be cleared before the page would successfully load after the error occurred.
